METHOD OF ROLLING.

Application filed December 19, 1921.

My invention relates to the manufacture of rolled metal shapes, knowngenerally as merchant shapes, and more particularly relates to thefinishing; operations whereby the size and the profile or contour of theshapes are fixed, and the surfaces are finished.

One object of this invention is the pro vision of a novel method ofmaking rolled metal shapes whereby roughness, irregularity, and othersurface defects are removed from the rolled shapes and. the shapes aremade accurate and with a finely finished surtaco, and "further objectsof the invention will be made apparent hereinafter, in the detaileddescription of the invention, and in the appended claims.

My invention broadly consists in grinding the shapes to size and contourafter completion of the hot rolling operation and while the shapes areheated to a temperature approximating that atwhich the hot rollingoperation is completed.

(he invention may be employed in finishing the shapes by subjecting theheated shapes to the grinding step of my improved method as they emergefrom the finishing pass 01? the rolling mill, or when the shapes havebeen allowed to cool the method n'iay be carried out by reheating theshapes to about the temperature at which they are ordinarily finished inthe rolling mill, and then grinding; the re-hcated shapes.

In the accompanying drawings, forming part of this specification,Figures 1 and 1 are plans showing the finishing rolls of a merchant milland one arran rmnent of grinding; apparatus adapted tor use in ca ry ingout my invention. A complete plan will be had by joining Figures 1 and 1on the lines [6"(6 of these figures.

Figures 2 and 2 are side elevations of the apparatus shown in Figures 1and 1 a complete side elevation being had by joining, these figures onthe lines (r -a thereof.

Figure 3 is a sectional end elevation of the apparatus shown in thepreceding figures, the seouon being taken on the line III-Jill 01 Figure2.

Referring now to the drawings, the letter A designates a stand offinishing rolls having finishing rolls 2 and 3 constructed and arrangedin the usual manner, and B designates the usual feed tables on oppositesides of the stand A, these teed tables having the Serial No. 523,383.

usual arrangement of apron plates a and table rollers 5.

The delivery end of the food table B abuts the receiving end 01 a hotrun-out table C which carries the rolled shapes away from the rollertable B and delivers them to the cooling bed l), upon which the shapesare allowed to cool and from which they are finally deli *ered to a coldrun-out table E.

A grinding mechanism l? is provided at an intermediate pointin thelength ol the table B, this grinding mechanism comprising a bearingstand (3 having a pair of vertical grinding wheels 7 mounted inadjustable bearing blocks 8, these bearing; blocks being mounted in thewindows of the hearing; stand 6, so as to be vertically adjustable.Adjusting screws 9 having handwheels 10 on the upper end thereof areprovided for moving and holding the bearing blocks 8 for the uppergrinding wheel 7 in adjusted position, and adjusting screws 9 also areprovided for moving and holding the lower grinding wheel 7 in adjustedposition. (See Figure 2a) The grinding wheels 7 will be formed of emery,carborundum or other suitable abrasive. These wheels are secured onsuitable shafts 11 which are rotatably mounted in the bearing blocks 8,and are provided with bevel gears 12 meshing with bevel gears 13 on thevertical drive shaft 1-1. The drive shaft 14- is provided on its lowerend with a bevel gear 15 which meshes with the bevel gear 16 on the endof the armature shaft 17 of the driving motor 18.

Positioned on the table B in front of or on the delivery side of thegrinding mechanism 1* is a pair of pinch rollers 19 and 20, these pinchrollers being rotatably mounted in a roller stand 21, and the upperpinch roller 20 being mounted in bearing blocks having adjusting screws22 by which the roller 20 is held in operative position relative to thelower pinch roller 19.

In carrying out my improved method with the above described apparatus,the sue ccssively rolled bars or shapes X pass directly from thefinishing stand of rolls A while still heated from the rolling operationinto engagement with the grinding wheels 7 of the grinding mechanism F,and engagement of the grinding wheels cuts away or grinds oil? anysurface defects on the rolled shapes the shapes being cut away to anequal depth througl'iout the length thereof so as to remove all surfacedetects and accurately finish the shapes to size and contour.

The pinch rollers being located on the feed table B in position toengage with the forward end of the shape being rolled be fore the rearend of the shape emerges from between the finishing rolls 2 and 3,enables the shapes to be pulled through the grinding mechanism F, evenwhen the shapes are small and flexible.

The advantages of my invention will be appreciated by those skilled inthe art. By the use of my improved method rolled shapes are finishedwith a degree of accuracy and with a surface finish which is notattainable with any of the old methods of which I am aware.

It is to be understood that the particular apparatus shown and describedis only illustrative, and that many changes in the construction andarrangement of apparatus usable in carrying out my improved method maybe made. \Vhile but one pair of vertical grinding wheels is shown in thedrawings, it will be apparent that the grinding nesaaea mechanism F mayhave horizontal grinding wheels instead of vertical grindine wheels orboth horizontal and vertical grinding wheels, and that a plurality otsets of such wheels may be en'lployed so as to permit of successivegrinding operations being performed on the shapes in the passage thereofalong the table B.

It also will be readily understood that the shapes may be re-heated andthen ground. although prel'erably they will be ground immediately alterthe completion ot the rolling operation.

1. The method of finishing rolled metal shapes, which consists ingrinding the shapes atter completion of the rolling operation and whileheated to a temjiierature approximating that at which the rollingoperation is completed.

2. The method of finishing rolled metal. shapes, which consists ingrinding the shapes immediately after completing the rolling operationand while still heated From the rolling operation.

In testimony whereof I have hereunto set my hand.
